Rod, connector, assembly toy set

Description

Rod and Connector Toy Construction Set}

The present invention relates to an assembly toy set, and more particularly, to an assembly toy set in which the main assembly element comprises a series of rods and connectors for coupling the rods.

A very popular form of this set of assembled toys is marketed under the trademark "K'NEX" by K'NEX Industries, Inc. Certain features of K'NEX assembled toy sets are reflected in US Pat. Nos. 5,061,219, 5,137,486, 5,199,919 and 5,350,331. The K'NEX assembled toy set was only introduced a few years ago but was very popular and commercially successful. However, despite the many advantages and many attractive features of the K'NEX assembled toy set currently on the market, a certain level of dexterity and finger strength is required to take full advantage of the many features offered. This will limit the marketability of existing assembled toy sets to children with significant dexterity.

The present invention relates to a rod and connector assembly toy set, which includes many key advantages of existing K'NEX assembly toys, while being designed and optimized especially for younger children. Thus, the components of the assembly toy set of the present invention are designed and made so that young children can assemble and disassemble the components to make various structures and assemblies with minimal dexterity and finger strength.

The rod and connector parts of the new assembled toy set are sized to fit a child's hand so that individual parts can be easily handled and handled by young children as young as four or five years old. For example, for rod members, rod diameters of approximately 3/8 inch are suitable for handholding and manipulating. For the preferred set of assembled toys of the desired type, these rods are provided in various lengths ranging from approximately 1 inch to approximately 9 inches. The main rod members of the new assembled toy set are made in a generally circular cross-sectional shape and are generally provided with ends and central body portions having a constant diameter. The end flanges and the central body portion are separated by a neck having a reduced diameter and a predetermined length.

The assembly toy set of the present invention further comprises connector members arranged to receive and hold the rod members in a fixed direction, so that the structures can be assembled. Preferably the connectors are provided with a hub, with one or more open ends radially with respect to the hub and with open sides. In a typical assembly toy set, the connectors may be equipped with one or more such eight rod coupling sockets. If more than one socket is provided, the sockets are generally arranged at a predetermined angle, for example 45 degrees.

According to a feature of the invention, the connector members are formed of a soft and flexible material which can bend easily in the region of the rod gripping socket. The sockets extend completely through one side to the other and are open on both sides. The sockets are formed with features for receiving and securing the flanged ends and neck portions of the rod members. This configuration allows the rods to be installed by a lateral snap-in operation, which lie within the neck of the rod, such that the socket is defined by the opposing recess contours of the rod gripping portions of the socket. It is axially aligned with the major axis of the receiver to be received and fixed. The flanged end of the rod member is received in the enlarged portion of the socket to prevent the rod from retracting axially from the socket in which the rod is installed. Due to the soft and flexible nature of the connector member, even a small child can easily assemble parts to form a structure. In addition, the rod-connector joints have significant elasticity and flexural performance, minimizing the possibility of injuries that can occur due to the dropping of a child, for example in the assembled structure.

Preferably, some of the rod members of the new assembled toy set are formed of a material that is somewhat harder and stronger than the connector members, although it has sufficient elasticity and flexibility to bend when it falls over, for example, during play. Can be. In addition, the rods may be provided in a softer, more easily bendable and flexible form, allowing the rods to be molded to a significant extent during assembly of the structure into set parts.

1 to 5 and the drawings described below, reference numeral 30 denotes eight pieces that are injection molded from a soft and flexible material, preferably a material having a hardness value of approximately 94 on the Shore A Scale. Pointing to a positional connector member having a mating position. More preferably, the plastic material of the connector member may be a product released under Grade 8402 under the registered trademark “ENGAGE” of DuPont Dow Elastomers. This is a thermoset olefin elastomer that is ideally suited for the required purpose. The material, released under Grade 8403 under the trademark "ENGAGE" from DuPont Dow Elastomers, is somewhat harder than optimized to make it difficult for young children to assemble and disassemble the parts of the new assembly toy set on the Shore A scale. Has a hardness value of. Grade 8401 of the same material from the same manufacturer has a hardness value of 85 on the Shore A scale that is softer than the optimal material and easily wears in the required environment.

The connector member 30 shown in FIG. 1 has a generally octagonal arrangement and ideally has an overall width of approximately 2.5 inches between the opposing sides 31, 32. The ideal thickness between the main front and back sides 33 and 34 of the connector is approximately 0.375 inches.

The connector 30 is provided with a central hub 35 that forms a cylindrical opening 36, as shown in FIGS. 1 to 5. The cylindrical sidewalls of the hub extend slightly below the front and back sides 33 and 34 of the connector such that the overall axial length of the hub is slightly larger than 1/2 inch.

A plurality of spoke shaped webs 37 extend radially from the hub 35 and intersect the octagonally arranged intermediate walls 38. The radial webs 37 and intermediate walls 38 preferably form a generally triangular space 39 formed by a web wall disposed in the central plane of the connector body.

The intermediate walls 38 arranged in octagon form the inner end of each of eight radially spaced rod-engaging sockets 41 formed by the connector. The sockets 41 are arranged on a radially arranged axis 42 spaced at an angle of 45 degrees. The socket 41 has a rod gripping portion 43 and a rod end receiving portion sized and shaped to receive and hold rods 45 of the type shown in FIG. 13. It consists of 44. These rods consist of an elongated central body portion 46 which has a generally cylindrical cross-sectional shape and forms the central portion of the rod and will be described in more detail below. At each end the rods are provided with a neck portion 47 of reduced diameter, and end flanges 48 preferably having the same diameter as the cylindrical contour of the body portion 46.

According to the present invention, the rod coupling socket 41 extends through one side of the main body of the connector 30 to the other side and is open on both sides. Preferably the rod end receptacles 44 of the sockets 41 closely match the size and shape of the end flanges 48 of the rods 45. The end flange portion 48 of the rod is received adjacent to the socket portion 44, but may pass through from one side to the other side.

In a preferred embodiment of the invention, the rods 45 have a basic diameter of approximately 0.375 inches in the body portion 46 and the end flange portions 48. The end flanges 48 are approximately 1/4 inch in length and preferably have clear oblique or chamfers, such as, for example, a 1/16 inch bevel at a 45 degree angle, at their outer ends ( 49). The interior 44 of the connector socket is shaped and dimensioned to closely match the previously described shape and dimensions of the end flanges 48 of the rods so that the end flanges fit snugly within the socket end 44. .                 

Preferably the neck portion 47 of the rods 45 is cylindrical in shape and has a diameter of approximately 0.250 inches, and in the preferred embodiment the opposite end faces 50 of the end flange 48 and the rod body 46. 51) has an axial length of approximately 0.320 inches. As shown in FIG. 5, for example, a connector socket 41 is formed by opposing sidewalls 52, 53 whose inner portions 52a, 53a engage the central walls 38. Within the rod gripping portion 43 of the sockets defined by the outer portions 52b and 53b of the side wall, the minimum spacing between the side wall portions (ref. 54 in FIG. 5) is determined by the neck portion of the rod ( 47) is significantly smaller than the diameter of these. In a preferred embodiment, the inlet dimension of the rod gripping portion is approximately 0.212 inches. The outer portions 52b, 53b of the sidewalls are formed of cylindrical grooves 55, 56 (FIGS. 4 and 5) coaxial to the socket shaft 42. The grooves 55 and 56 form an arc of a cylinder of approximately 0.250 inch diameter. The neck portion 47 of the rod member 45 can be inserted into the rod gripping portion 43 of the socket under the lateral force (from the other side). In particular, with the end flange 48 of the rod aligned with the inner socket portion 44, the axis of the rod is aligned parallel to the axis of the socket, and the rod is laterally forced into the socket. All. In the state of lateral force acting on the rod, the neck portion 47 of the rod is elastic to allow the neck portion 47 of the rod to be inserted into the opposing grooves 55, 56. Opposing side walls 52, 53, which are deformed, are forced apart. Preferably, the outer portions 52b, 53b are tapered in both directions, as shown in FIG. 4, so that the outer portions 52b, 53b are outward as the rod is pressed laterally in the socket. Make it easy to move When the neck of the rod lies between the opposing grooves 55, 56, the rod is firmly grasped, thereby axially aligned with the socket shaft 42. The end flange 48 of the rod is received in the socket portion 44 to fix the rod so that it does not move along the axis in any direction.

To help young children easily assemble and disassemble, the force required to laterally insert rod 45 into the rod gripping socket should not be too large. At the same time, it should be possible to properly hold and secure the rod in the socket 41 so that a useful structure can be assembled. The cylindrical grooves 55, 56 preferably correspond to an angle 57 between 60 and 70 degrees, more preferably approximately 64 degrees. For the material designated for the connector, appropriate proportional power is provided by these proportional grooves 55, 56 without inappropriately hindering the assembly and disassembly of young children.

In a preferred embodiment of the invention, the side walls 52, 53 of each of the adjacent pairs of rod coupling sockets 41 are joined by overall circumferential outer walls 60 defining the outer peripheral walls of the connector. . The walls 52, 53, and 60 form a generally triangular opening 61, and preferably a quadrilateral tongue member consisting of the side walls 52, 53 and the connecting outer wall 60. While adding rigidity to the 63, the opening 61 is closed by a central panel 62 disposed in the central plane of the connector body. As shown in FIG. 1, the tongue-shaped members 63 distinguish pairs of adjacent rod coupling sockets 41 and are defined by radial walls (webs) 37 and intermediate walls 38. Is coupled to the inner body portion of the connector.

The peripheral walls 60 function in various ways. The peripheral walls 60 provide a dull and smooth contact area to minimize the chance of being injured when inadvertently contacted. In addition, by connecting the rod gripping portion of one socket with the corresponding rod gripping portion of the adjacent socket, each peripheral wall 60 helps to support the other peripheral wall 60 to some extent. This is desirable in view of the soft, flexible plastic material applied to the connector.

In the modified socket of FIGS. 6 to 8, the connector 70 is formed of five rod coupling sockets 41 and is also spaced at an angle of 45 degrees in the radial direction. The basic structure and arrangement of the sockets 41 and other main members of the connector 70 are identical to those of the connector 30 shown in FIG. 1 except where noted. The important difference is that the rod coupling sockets 71 and 72 at the distal ends of the connector body have no neighboring socket on one side. Thus, it is desirable to form the outer walls of the sockets 71, 72 with ribs 75 to reinforce the outer sidewalls 73, 74. The rib 75 preferably extends along the base wall 76 of the connector from one end portion to the other end portion. Thus, the sidewalls of the central sockets are provided with supporting means from the connected sidewalls of the neighboring sockets, while the outer sidewalls of the socket at the distal ends depend on the rib 75 for this reinforcement.

2 and 8, it can be seen that in the case of FIG. 2, the hub 35 is provided with a cylindrical passageway (opening) 36 extending from one end in the axial direction to the other end. In contrast, in the case of FIG. 8, the hub 77 is formed of a central dividing wall 78 and a plurality of inner annular gripping ribs 79. As shown in FIG. 2, the through passage 36 may be provided in any type of connector. However, it is preferable that through hubs are provided in the hubs, particularly for those selected from the octagonal connector members 30 as shown in FIG. 1. Preferably other socket arrangements and certain other octagonal sockets may be provided with a blocked passage provided with a dividing wall 78 as shown in FIG. 8.

As shown in FIG. 12, the hub 77 is formed of three annular ribs 79 on each side of the central wall 78. The minimum diameter dimension of the annular ribs 79 is slightly smaller than the diameter of the end flanges 48 of the rods. The root diameter, which is the diameter of the spaces 80 between adjacent ribs 79, is preferably slightly larger than the diameter of the end flange 48. Thus, the end flanges 48 have a diameter of 0.375 inches, the minimum diameter of the ribs 79 is preferably approximately 0.370 inches, and the root diameter 80 is preferably approximately 0.380 inches. When the rod end 48 is inserted into the open end 81 of the hub recess, the annular rib 79 is deformed and inflated so that the end flange 48 as in the example shown in FIG. 20. Secure it firmly. This configuration allows rods and connectors to be stacked by longitudinally inserting the rods into the blocked hub recess, as shown in the example of FIG. 20.

9 to 11 show other forms of connector members 90 and 91 formed of four and three rod mating sockets, respectively. The structural feature of the connector members 90, 91 is that the sockets 41 are arranged at an angle of 45 degrees, and at the distal ends the sockets 71, 72 are identical to the reinforcing ribs 75 of FIG. 6. It is substantially the same as the connector member 70 shown in FIG. 6 in that it functions in a manner and is supported on one side by the reinforcing ribs 92 and 93. All of the connector members described above are formed from a soft, flexible plastic material, such as the thermoset olefin elastomer "ENGAGE" grade 8402 described above.

In a preferred embodiment of the present invention, the main rod members 45 are formed of a material that is harder and more rigid than that used to form the various connector members. Preferably, the main rod members may be formed of general purpose polypropylene such as those released under the trademark Hipro's registered trademark "PRO-FAX". Materials sold in Rockwell hardness 105 (R scale) "PRO-FAX" 6331 NW are suitable. The rods are preferably shaped into a series of lengths based on a right triangle arrangement. Thus, longer rods of a series of length rods are suitable for installation along the hypotenuse of an equilateral right triangle formed using three connectors, the right side of the triangle being the next of the series of rods of length. It is formed of two rods of short length. Two short sides of the right triangle are made by adding the length of the shorter rods and the distance from the inner ends of the rod coupling sockets to the central axis of the connector hub. Likewise, the total length of the hypotenuse of the right triangle is made by adding the length of the longer rod and the distance from the inner end of the connector sockets to the center of the hubs of the connectors to which the rod is coupled. The shortest of the series of rods is preferably the length that the two connectors join side by side to substantially contact the outer walls 60. The maximum length of a series of rods is theoretically unlimited. However, as a practical matter, a rod length of approximately 8.7 inches in total is a suitable maximum length for a typical assembly toy set.

Preferably the body portions 46 of the rods 45 are not formed of a rigid cylinder, because they are not necessary for strength and unnecessarily increase in weight and cost. Preferably, the body parts 46 are made in the shape of ribs as shown in FIG. The central web 100 extends along the diameter of the rod body from one side to the other side. Ribs 101 and 102 extend apart from each other at right angles from the central web. At the outer distal end the web 100 and the ribs 101, 102 form a cylindrical envelope corresponding to the cylindrical outer surface of the end flanges 48.

As shown in FIG. 13, the neck portion 47 of the rods is preferably formed with relatively sharp edges 103 and the neck portion engages the end face 50 of the end flange 48. do. At its opposite end, the neck is coupled to the end face 51 of the rod body 46, for example, with a generally round fillet of 0.04 inch radius.

The shape of the ends of the rods 45 preferably matches the shape of the connector sockets 41 tightly. The neck portions 47 are formed approximately 0.320 inches in length between the end faces 50, 51, and the inner shoulders 105 of the socket and the connector as shown in FIG. 17. Substantially the same dimensions between the outer sides 31 are used for the length of the rod gripping portion 43. In so doing, the connector is fully and firmly fitted and connected to the rod.

As shown in FIG. 4, the side inlet surfaces 104 are tapered intensively toward the grooves 55 and 56 having a cylindrical shape to laterally enter the rod neck 47 into the gripping portion. Makes it easy. In a preferred embodiment of the invention, pairs of opposing faces 104 may be arranged symmetrically with an angle of approximately 22 degrees to each other.

Although it is contemplated that rods and connectors are assembled and disassembled by lateral movement of the rod end into and out of rod gripping socket 41, due to the nature of the soft and flexible material from which the connector is formed, and the assembly toy set Due to the nature of the relatively inexperienced young children expected to use, the rods can be forcibly separated from the connector in other ways. For example, the connector may remain static while the rod associated with the connector is forcibly moved by its outer end on the same plane as the connector. When sufficient force is applied in this manner, the connector socket 41 is forcibly opened and one side of the rod end 48 is forcibly moved under its retaining shoulder 105 such that the rod Forced out through the open shear of (41). In the rod and socket configuration of the described embodiment, such a configuration makes it possible to minimize damage to the connector member due to the shape of the rod end and the end 44 of the socket. Thus, the generally rounded inner edges 106 of the rod 45 allow the threaded rod to slide past the shoulder 105, while avoiding excessive wear of the soft plastic material if necessary. The inner corner edges 105a of the shoulders 105 are preferably slightly rounded, for example with a radius of 1/32 inch. In addition, the threaded outer shear 49 of the rod end, ie end flange 48, easily retracts the threaded rod from the socket 41 while avoiding excessive wear. By doing so, it becomes possible to make the connector members of a soft and flexible material so as to avoid excessive wear of the connectors and to be safely and easily operated by an inexperienced user.

As a preferred form of the assembled toy set according to the invention, based on the triangular chain relationship described above, the shortest rod in the series of rods is of the same plane with its outer surface portions substantially facing, as shown in FIG. 15. It has a length for joining the two connector members (110, 111) placed in. Thus, the shortest rod 112 shown in FIG. 15 has a uniform diameter having a length that generally corresponds to the length of the two neck portions 47 of the longer rod members 45 as shown in FIG. 13. It consists of a pair of opposing rod ends 113 connected by a cylindrical portion 114 of. In the set of assembled toys of the general dimensions mentioned so far, the overall length of the short rod 112 is approximately 1.170 inches.

For safety, the rod of FIG. 15 is provided with a plurality of outward recesses 116, 117 at its opposite ends 113, the recesses having several corners around the opposite end edges of the rod. Form the corners 118, 119. The purpose of these corners is to stimulate the rod when it enters the mouth of a young child. In this case, if the corners and / or edges 118, 119 touch the area near the throat or bronchus, they may preferably cause nausea and as a result may be removed before the rods cause problems.

Certain rod members, particularly long rod members of the assembled toy set, are preferably relatively flexible and capable of bending. This allows the flexible rods to join the structure in various shapes and contours. Thus, a selection of longer rods can be molded from a relatively soft and flexible material such as Monprene MP 1805 released by QST, Inc., St. Albans VT. . The material having a hardness of approximately 90 on the Shore A scale is more flexible than the material of the connector member and can be easily bent into various shapes. The basic cross section and external configuration of the bendable rods is the same as the rod made of harder polypropylene material, such as rod ends, necks and body parts, except that more flexible rods can be bent. In all respects it functions in the same way as harder and tougher rods. In a particular assembly toy set according to the present invention, even some of the longest (eg 8,7 inch) rods are preferably made of Monprene MP material.

As shown in Figs. 19 and 20, the other types of hub structures provided in the connector member allow the user to perform other functions as desired. For example, as shown in FIG. 19, the connector 30 is provided with a hub 35 having a smooth cylindrical opening 36 extending completely through the hub. The rod 45 may pass through the opening 36, and the central body 46 of the rod is rotatably or rotatably supported inside the connector member. The rod is also slidable within the hub as will be described below.

As shown in FIG. 20, the hub 77 is formed of a central dividing wall 78 that is formed with opposing blocked recesses 77a. Ends 48 of one or two rods 45 can be inserted into the blind recess and secured therein by the annular ribs 79. Preferably the depth of the blind recess is approximately 0.250 inch and approximately equal to the axial length of the rod ends 48 such that the rod ends are fully received and fixed by the hub recesses 77a. This structure provides a great deal of flexibility in the design of assembly toys that can be made into a new assembly toy set, and above all allows the connector members to be laterally spaced apart and connected together.

21 and 22 show another configuration for assembling the rods 45 to the connectors 30, 70, 90 or 91 at right angles to the plane of the connector. This configuration can be obtained by placing the rod at right angles to the connector and pushing the neck 47 of the rod into the open outer end of the connector socket 41. The diameter of the neck portion 47 (approximately 0.250 inch) is somewhat larger than the socket opening (approximately 0.212 inch) defined by the outer socket walls 52b, 53b, which causes the rod neck 47 to be laterally lifted. In order to be inserted into the socket, the socket needs to be forcibly opened to some extent, and is received by bending the tongue-shaped member 63 laterally.

The rod 45 is pushed into the socket 41 until the neck portion 47 reaches the enlarged rod end receiving portion of the socket (FIG. 21), ie the socket portion 44. At this time, the socket side walls 52 and 53 are elastically closed to their normal positions so that the neck portion 47 is accommodated in the socket portion 44.

In a more preferred embodiment according to the invention, the axial length of the neck portion 47 is somewhat smaller than the thickness of the connector 30 between its sides 33, 34. For example, while the axial length of the neck portion 47 is approximately 0.320 inches, the thickness of the connector 30 may be approximately 0.372 inches. Thus, when the neck portion 47 is pressed into the socket 41, the sides of the shoulders 50, 51 are formed on the sidewalls 33, 34 of the connector, as shown in the side view shown in FIG. 22. At the opposite ends of the neck 47 facing the face, the shoulders 50, 51 engage the sidewalls 33, 34 of the connector and press inwardly. This allows the rod and the connector to fit snugly as desired when assembled in the manner described.

More preferably, the cylindrical neck 114 of the short rod 112 has an overall length of approximately 0.670 inches. This length is somewhat smaller than the thickness of two adjacently disposed connector members. Thus, the shortest rod 112 can also be installed laterally in a pair of adjacent connector members, thereby joining the connectors together in this configuration.                 

조립 완구 세트와 많이 유사하지만, 이에 많은 장점이 부가되기도 하여 중요한 부분에서 서로 다르다. 차이나는 장점 중의 하나는, 상기 로드들의 단단한 소재에 비하여 상대적으로 부드러운 소재로 되어 있다는 것이다. 다른 장점은 상기 커넥터 소켓의 로드 그리핑부가 상기 로드들의 목부분들을 결합하고 고정하여 상기 로드들을 상기 로드 그리핑 소켓들에 축방향으로 고정시킨다는 것이다. 상기 커넥터 소켓 내로 측방향으로 상기 로드의 목부분을 삽입하거나, 커넥터들에 구비된 막힌 오목부로 플랜지가 달린 로드 단부를 삽입함으로써, 로드들이 상기 커넥터들에 측방향으로 결합된다는 점에서 결합방식이 다르다. The assembled toy set according to the present invention is particularly suitable for use by young children whose dexterity and finger strength are not well developed. Relatively large connector members and rods make it easy for young children to grip and manipulate with small hands and, in combination with the soft and flexible nature of the connector member, makes it easy to assemble and disassemble parts with small hands. Is especially important. Components of the new assembly toy set are well known K'NEX

It is very similar to the assembled toy set, but it also adds many advantages and differs in important ways. One of the differences is that it is made of a relatively soft material compared to the rigid material of the rods. Another advantage is that the rod gripping portion of the connector socket engages and secures the neck portions of the rods to axially secure the rods to the rod gripping sockets. The coupling is different in that the rods are laterally coupled to the connectors by inserting the neck of the rod laterally into the connector socket or by inserting the flanged rod end into the blind recess provided in the connectors. .

The soft and flexible nature of the connector members is not only an important feature for safety, but also allows the installed rod to be deformed against unintended contact. In addition, the rod inserted laterally into the rod gripping socket allows the bit in the plane of the connector to be removed by movement. Even if the rod was not intended to be removed in this way, it can be seen that immature children can frequently manipulate parts in an unintended manner and that the assembly toy set according to the invention is made for this behavior. .

The relatively large parts themselves are a safety feature in that small, immature children will not try to put large parts into their mouths. Even if children try to do so, it is unlikely that it will cause pain. Even for smaller loads, there is an additional safety feature that minimizes the chance of accidental suffocation by increasing nasal congestion by increasing the likelihood of parts spitting.

Of course, it is to be understood that the specific forms of the invention described herein are for illustrative purposes only, and that certain modifications may be made within the scope of obvious facts from the disclosure. Accordingly, reference should be made to the appended claims to determine the full scope of the invention.
